Aerial supporting mast



June 13, 1933. A. LEBOURG AERIAL SUPPORTING MAST Filed Nov. 1'7, 1950 gme'ntot 4564500071 Patented June 13, 1933 UNETED STATES ADOLPHE LEBOURG, OF GADSDEN, ALABAMA AERIAL SUPPORTING MAST Appiieation. filed November 17, 1930.- Serial lie. @6300.

This invention relates to means for supporting the aerials of radio sets and has for a primary object the provision of a durable mast adapted for ready attachment on a roof or other base.

Another object of the invention is the provision of a steel mast of this character formed of a single length of a steel rod bent to provide leg portions adapted to straddle a roof ridge and formed of means whereby the mast may be attached in position.

The embodiment herein disclosed constitutes the best means I have thus far devised for reducing the invention to practice. In the drawing:

Figure 1 is a perspective of a mast constructed in accordance with the provisions of this invention and as mounted in position upon a gable roof structure.

Figure 2 is an end view thereof.

Figure 3 is an elevation of a slightly modilied form of mast.

Figure 4 is an elevation of the bottom of a mast and illustrating the manner by which the same is attached to a flat roof structure.

In detail the improved mast consists of a single length of steel rod material, or a suitable substitute, which is looped upon itself at its center through several turns to provide a top loop from which point the rod is extended to form diverging arms 11 and 12 of the necesasry length tosuit service requirements. At their lower ends the arms 11 and 12 are bent upon themselves to provide fiat loops 13 and 14 respectively, which flat loops are outturned with respect to the arms 11 and 12 at an obtuse angle to provide, in effect, attaching legs.

Beyond the loop or attaching leg 13 the rod material is continued as a diagonal brace 15 which is attached at its end to the arm 12. As shown in Figures 1 and 2, this attachment is accomplished by looping the end of the brace about the shank of the arm 12 in the attaching loop 16. In like manner the material of the rod is continued from the attaching leg 14 in a diagonal brace 17 which extends to and is attached to the arm 11 by an end loop 18 similar to the end loop 16 of the brace 15. At the point of intersection of the braces 15 and 17 one of these braces, such as I 17, is connected to the other by a central loop In the modified construction shown in Fig ure 3 the'central attaching loop 10 is merely 55- a single flat bend and the arms 11' and 12 spot welded as at 20 at their apex adjacent attaching loop 10. It is not even necessary that the arms 11. and 12 be of one piece. I As long as they are spot welded at 20, the same rigid efi'ect results. At their lower ends these rods 11 and 12 are formed with attaching leg loops 13 and 14 as in the preferred embodiment but in this type of construction the diagonal braces 15' and 17 are connected at their ends to the respective arms 11' and 12 by spot welding as at 21 and 22 respectively. At the point of intersection the two diagonal braces are connected by spot welding as at 23. In certain types of mast construction it is desirable to have one-side longer than the other and such a construction-is illustrated in Figure 3 wherei1IJ1L- the arm 12 is made longer than the arm r VVhen the mast is intended for use on gable roof structures indicated generally as at 24 in Figures 1 and 2, it is disposed over the ridge of the roof with the diagonal braces 15 and 17 substantially engaging against the 53 sloping root sides up to their point oi. connection 19. Attaching elements, not shown, are then disposed through the leg loops 13 and 14 by which means the base of the mast is securely anchored to the roof. A guy wire 53 25 is connected between the root and the top attaching loop 10 of the mast and the aerial 26 is likewise connected to the upper attaching loop 10 forming the guy at the opposite side of the mast.

When the mast is intended for use on flat root surfaces it is disposed as indicated in Figure 4 wherein the fastening elements 27 are driven through the loop legs 13 and 14 into the roof 28.. 53

In all of the forms as illustrated it will be apparent that the mast is a substantially flat one piece construction or equivalent in which the various arms and braces occupy substantially a common plane. In the forms shown in Figures 1, 2 and 4 the aerial and guy wires are connected to extend from opposite side faces of the mast but in assemblies wherein the aerial support is disposed substantially in the plane of the mast body the longer arm construction, such as 12, is advantageous in providing a brace in addition to the supports and attachments previously described.

I claim:

1. An aerial supporting mast comprising a metal rod bent upon itself at substantially its central portion and extended therefrom in diverging arms, the ends of the arms being bent upon themselves to provide base attaching legs, and the rod being extended diagonally from the attaching legs upwardly into contact with the opposite arms to form braces, said braces being connected at their point of intersection and having attaching connection at their ends with the respective arms.

2. An aerial supporting mast comprising a single metal rod of substantially triangular formation and having its end portions extended diagonally across each other and attached to the respective diverging portions of the rod adjacent their lower ends.

3. An aerial supporting mast comprising arms diverging downwardly and outwardly from a point of contact, the ends of said arms being bent upon themselves to form attaching legs and then extending diagonally upwardly and across each other to a terminal contact with adjacent arms, and fastening means at the points of contact.

4. An aerial supporting mast comprising a pair of arms diverging downwardly and outwardly from a point of contact, the ends of said arms being bent upon themselves to form attaching legs and then extending diagonally upwardly and across each other to form a base adapted to straddle a roof ridge, one of said arms being longer than the other to form an additional brace when an aerial is supported in the plane of the mast, and fastenmg means at all points of contact of said arms.

In testimony whereof I afiix my signature.
